After the History Channel stopped producing real history documentaries and started focussing on pseudo-scientific studies (UFOs and such) as well as pseudo documentaries (Pawn Stars) which they are very successful with by the way, they also tried out actual TV shows. The drama series Vikings is one of them.

Similar to the previous seasons, only censored versions aired in the US. Besides numerous plot cuts, further alterations had been made: Any sex scene and all kind of nudity had either been completely remooved or replaced by alternate, less explicite footage. As for the violence, only one of the episodes (3x06 "Born Again") contains more graphic footage.

The last 3 episodes of this season (3x08 "To The Gates!" & 3x09 "Breaking Point" & 3x10 "The Dead") do not contain any alterations by the way. Since these are the episodes that show the attack on Paris, I guess no alterations were required.
